' Application filed March '19, 1917. Serial No. 155,65a.

To all whom it may concern: I

Be it known that I, GEORGE F. BRANDT, a citizen of the United States, residing at "Boston,'county of Suffolk, State of Massachusetts, have invented an Improvement in and its object generally is to provide a novel various changes may be made within its v the normal groove supply and to take up and improved construction of feed.

The feed is that portion of the fountain pen which conducts-the ink from the reser-- voir in the barrel to the nibs ofthe pen, and,

in the usual construction-the ink frequently.

have been'provided in the feed-bar which communicate directly or indirectly with the groove in the feed-bar with the frequent result that the ink 'can'ea'sily flow to'these pockets, be there briefly stored and suddenly dislodged in large blots. Broadly, to obviate this disadvantage there have been provided a plurality of grooves on'eachside of the feed-bar adjacent to, but not communicating with, the usual median groove which feeds the ink directly to the pen nibs. These grooves are preferably connected by a trough so they are.intercommunicating.

Other objects and features of the invention will more fully appear from the following description and the accompanying drawings and will be pointed out in the an-.

'nexed claims.

vIn'the accompanying drawing there has been disclosed a construction designed to it carry out the objects of the invention, butit is to be understood that the invention is not confined to the exact features shown, as

reasonable scope.

In the drawings, v I Figure 1 is a side elevation of the fountain pen with the cap shown in section;

Fig. 2 is a side elevation of the feed-bar;-

fig. 3-is a view of the grooved side of the same;

Fig. the line 4r4 of Fig. 3.

In the selected embodiment shown in the drawings there is disclosed a fountain pen 4 is an enlarged sectional detail on having the usual, generally cylindrical, barrel 1. The barrel may be of any suitable shape or type, self-filling or otherwise. The point section 2 of the barrelreceives therein the feed which comprises thenovel feed-bar 3 and the usual pen 4. The inner "end 5 of the feedebar is substantially cylindrical'in shape and fits snugly within the'point sec tion 2'. .The pen 4 is placed upon the upper face of the feed-bar and also has its heel or endopposite the nibs snugly positioned within the end of the point section. This novel feed-bar has the usual median longitudinal groove 6 which extends from the endof the cylindrical portion 5 to a point adjacentthe outer end and is here disclosed as having the usual groove slits 7 The function of this groove 6 isto provide a small duct to permit passage of ink from the supply in the barrel 1 to the nibs of the pen 4.

. vDne important feature of this invention consistsin theprovision of a'plurality of small grooves to take up and retain any abnormal flow of ink when the pen is in use-due to a variety of causes. For example, the sudden warming of the fountain pen by contact with the hand may cause a sudden expansion ofthe barrel content and result, as. do sudden jars, in causing the feed-bar to become flooded. These grooves are formed in the feed-bar, at its outer portion, and are thus beneath the pen 4: when Patented May28, 1918.

the parts are assembled into a working device.

These grooves Sin the preferred form shown are milled in the outer portion of the feed bar, are preferably parallel and are formed at an oblique angle to the main feed 1 groove 6, and, as here shown,1 slant .in a downward direction when the pen is held in normal working position. They functionto retain and storeany ink that may leak from grooves 8 aids the return of the, ink to the su ply in the barrel 1,

referably thesegrooves are made 'iutercommunicating. A selected embodiment of such novel structure is best disclosed in Figs.

3 and l wherein troughs 9 are cut substan tially paralleling the median longitudinal groove 6. @no such trough is provided on each side of the groove 6 and connects each side series of grooves 8. The troughs are comparatively shallow cuts extending across the ribs 10 which separate the grooves 8. By this provision, the complete filling of one groove while the others are empty is prevented, as the filled groove rnay communicate a portion'oii its excessive supply to the adjacent groove on the same side. Similarly, facility of ire-flow to the barrel 1 is afforded. 'lhese intercornrnunicating troughs 9 do not communicate with the median groove and preferably extend only from the first to the last groove 8. ln this embodiment of the invention there is preferably employed a, pair of supplementary channels ll These supplementary channels are each relatively enlarged and are capable oi holding a greater quantity of surplus inlr than any of the similar grooves 8. The troughs 9 extend and connect these suppleinentary channels ll with the grooves 8. These relatively large supplementary channels'll, which thus communicate with all the grooves on the same side of the main groove serve as a supplementary well for the holding of any surplus ink. 'lhey are particularly useful when excessive flooding oil a pen occurs due to the rapidity of ink how when the supply is approximately enhausted.

While there has been shown herein aselectcd embodiment of the invention, it is to be understood that the construction is illustrative but not restrictive and that the same may be modified within the meaning and scope of the claims which follow.

Having fully described my invention, what ll claim as new and desire to secure by Letters Patent is:

1. A fountain pen including a feed loar having a longitudinal teed-groove and having a plurality of grooves independent of said teed-groove on either side thereof, and troughs extending longitudinally of and nally of and effecting direct intercoininunication between said grooves.

3. A fountain pen including a feed bar having a longitudinal teed-groove along the median of its upper face, a plurality of grooves cut in each side of the bar, each groove extending from a point adjacent the feed-groove and non-communicating therewith to a point adjacent the under face of the har, and a longitudinal trough extending on each side of the teed-groove intersecting each groove whereby the grooves on each side are interconimunicating.

i. A fountain pen including a feed-bar having a longitudinal feed-groove along the median of its upper face, a plurality of grooves cut in each side of the bar adjacent said upper face, an enlarged supplementary channel at each side of the feed-groove and nearer the inner end of the feed bar, and a longitudinal trough on each side of the feed groove and connecting the grooves and the channel on each side.

5. A fountain pen including a feed har having longitudinal feed-groove along the median of its upper face,'a plurality of grooves in each of the sides of the bar ad jacent said teed-groove, said grooves being formed in said sides at an acute angle tothe downward worlnng flow of the ink so that any surplus, may readily flow into the grooves and re-fiow to the barrel supply when the fountain pen is held in normal inverted position, and troughs extending longitudinally of and efl'ecting direct intercominunication between said grooves.

ln testimony whereof I have signed my name to this specification FRANKLHI BRANDT
